Current Behavior
When I attempt to subscribe to a topic which doesn't exist localstack succeeds and returns a subscription arn.
user@XYZ:~$ awslocal sns subscribe --topic-arn "arn:aws:sns:us-east-1:000000000000:topic-does-which-does-not-exist" --protocol sqs --notification-endpoint "arn:aws:sqs:us-east-1:000000000000:my-queue"
{
"SubscriptionArn": "arn:aws:sns:us-east-1:000000000000:localstack-topic-does-not-exist:8c98427f-bfea-4b0f-88ab-4a377e113312"
}Performing the same action against an aws account:
user@XYZ:~$ aws --profile my-aws-profile sns subscribe --topic-arn "arn:aws:sns:eu-west-1:123456789012:topic-does-which-does-not-exist" --protocol sqs --notification-endpoint "arn:aws:sqs:eu-west-1:123456789012:my-queue"
An error occurred (NotFound) when calling the Subscribe operation: Topic does not existExpected Behavior
To return the topic does not exist error in line with the aws behavior.
